To all whom t 'may concern:

Be it known that l, ARTHUR. E. BLAsI-IILL, a subject of the King ofGreat Britain, residing at the city of 'Vestmount in the Province ofQuebec, Dominion of anada, have invented certain new and usefulimprove-y increase the. efficiency of machines for this' purpose andreduce the weight of the operating parts thus enabling a higher speed ofoperation to be obtained. ri further object is to produce a fabrichaving greater durability.

The invention may be said briefly to consist of a machine comprising aseries of distinctlock-forming mechanisms, means for causing the metalfrom which the lock is 'to be formed to enter the lock-formingmechanisnis, and operating means common to the series of lock-formers.More specifically stated the invention may be said to consist of meanswhereby the wire from which a staple 'is formed is fed in a direct lineto position to be cut and formed into a staple, means wher by the staplethus formed is guided or controlled and advanced while lying in the sameplane in which it is formed to posit'on engaging the intersection of thewires;

series of independently carried and relatively adjustable lock-formingmechanisms whereby a lock is formed and simultaneously canned to lockthe intersection of a pair of wires; a feature in conjunction with themeans last mentioned being that cach lockforming mechanism includes as acompenont part a safety device automatic in its action. A furtherfeature consists in combining with the machine parts proper a devicehaving the dual function of a coiler and a tension device, thusobviating` the use of a separate tension and thel separate ceiling orcrimping devices. A feature of the invention consists of means wherebythe stay wire is fed continuouslythat is to say, is-

projected from the feeding means continuously-the wire thus projectedbeing stalled however during a momentary period while being eut, `and incombination,l withfthis means 'I provide means whereby the staywires arecut into stays lof predetern'iined uniform length, another novel featureconsisting of this last-mentioned means being that the feed devices areprevented from'injuring the galvanizing on the wire while `it is beingcut. Other features n consist of `fa particular combination of partswhereby the shft-ing of t-he stays from the positionto which they arefed to weaving position facilitated; means for facilitating the twistingof the stay-wire around the top land bottom strands; means for taking upthe webas it is woven; and the' invention also conssts Of thecombinations, construction, and "theI par# ticnlar arrangements of partshereinafter described and illustrated.`

Figs. 35 and 3G are side elevation and vertical sectional View,respectively, of the main member of the combined coiler and tensiondevice.

The machine frame consists of frame members 2 and 3, united by a pairoi' upper beams 4 and 5 and a lower beam 6, the upper beams serving astablesfor supporting parts of the operating gear to be presentlydescribed. The machine member 2 has a slideivay 2a covered by a cap 2band a boss 7 overhanging open horizontal frame portion 8- having an arm9 supported from the base by a column 10. rlhc tables 4 and 5 havefastened thereto the series of lool: formers, by which a series et'locks are formed and simultaneously made to lock together theintersecting strands and stays Which are indicated at 12, 14 and 15 and20 respectively, the reference numerals 12 and 14 indicating the top andbottom strands respectively and 15 the intermediate strands. The lockformers of the series are the same in every respect, and consequentlyonly one need be described.

Each lock-former comprises devices tor feeding the locking-Wire, cuttingstaple lengths therefrom, and forming them rst into staples and then thestaples into locks embracing the intersecting strands and stay- Wires.'The devices are all located in a carrier rigidly secured upon thetables 4 and 5. Each carrier consists oi a box-like casting 25 having anangular extension 26 oi substantially inverted T-form, one flange 27 otwhich is ot greater depth than the other 38 and formed with an uprightflange serving as a guide for a plunger 30 by which, in conjunction Withan intermittently hori- Zontally reciprocatory pin 31 (to be hereinatterfurther described), the staple is formed. The end of the angularextension opposite to the box-like member is turned as at 27"L to extendat right angles to the table portion 5 upon which it rests. The

connection between the extension 27a oi each casting and the table 5consists of a series of spaced grooves 500 and a f 501 inserted halfinto either one ot' a pair of grooves 502 in the underside et theextension and half into one ot the grooves 50G. rlhe grooves 500illustrated in dotted lines, Figure 10, and 502 are, respectively,spaced one half inch and one inch apart in order to enable a one-halt'inch adjustment to be had; these parts being in this manner held againstdisplacement in parallel planes, ative displacement at riglt anglesbeing prevented by a bolt 505. This plunger 30 consists of a member etoblong cross section each side edge having a tongue 28 and one end beingreduced in thickness as at 32, While a flat groove 33 extends throughoutone side and is deepened as at 25%, sce Figure 15, Within the thickerportion of the plunger. The groove accommodates and acts as a guide fora second plunger by which the staple is yforced into dies for forming itinto the lock. This second plunger consists of a flat bar 40 formedwith1 a 'fixed die is indi Menzies lateral hook l1 engaging a hook 42 oncross-head 13 having side flanges it in alineinent with the sides or'the plunger bar 40 which is ot greater' width than the main body ot thecross-head. The plunger-bar is guided in the flat groove and thecrosshead in the deeper portion 29 of the groove. The width or theplunger 30 from the plunger L10 to the bottom is equal to onehaltthelength required tor the sta}' leblank, the bottom and toptongues Q8Vslidalily engaging the groove formed by the flange 29 and acorresponding groove formed in a cap 15. The cap extends trom end tolend of the angularl extension 2G to the top oi which it is secured byscrews 28a.

The staple formed by plunger 3() and pin 31 is toi'ced by plunger 1-0into a matrix presented by a pair oi dies carried within the adiacentend oit the member E25, one die being xed and the other movable. Thelated at 50, and it is secured by acapscrew 51, or othersnitable means7to the interior of the endr ot the boi; and held against verticaldisplacen'ient, The particular formation of the matrix face oi' this diewill be presently further described. A slot extends .tronir this matrix'tace through the die in alinement with the guiding slot for plunger d()and such face is grooved as at 61 and 62 to accoi'nmodate theintersecting stay-wire and strand. The movable die indicated at 353 ismounted in the end of a slide 70 by a vertically, disposed dovetailconnection 7 This slide located within the boxelike casting 25, the'free end or which overhangs the beam l 'and is toi-hed as at 72 toafford* bearing for a shaft 73 to be presently further referred to. Uponthis shaft is rigidly mounted a cam 74 which bears upon trundle roll 75mounted rotatably upon a iffransverse shai't 7 6 the ends of which areconi'ined in horizontally disposed forked.

an extension of the link-member 7 8, a setscrew 94 extending through thelink-member and bearing upon the bottom ot the' box for the purposeotadjusting the degree to which the toggles lie ori-center. The link 7Sis connected to links 77 by an ad- 'justable member 78 pivotallyconnected to the links 77 by a pin 90 and a rightand-le'ft-hand screw 91connecting the mem-V bers 78 and 7Sa together. This screw affords meansrfor adjusting the length between the shaft 76 and pin 79 for initialifittingand to take up the wear between the cam 7 l and litecte'd bya'laterally inovablebar 100 coinmon to all the lock-formels. This barwill be hereinafter more fully described. The face of the matrices aretermed follows The matrix has a pair of curved groovesy oet cofacting`withgrooves in the face of matrix 50 and apair of grooves o 66 andf 67in each matrix face accommodating the strand and stay-wire respectively;v

while the matrix t'ace 63 has a. pair oi concavities 68 and 69 toaccommodate the ends of the staple. i

Before kthe staple can be vformed a wire blank length must be cut andfed ,to posi-v tion to be acted upon by the staple-kilorniing plungersandthe cutting thereof is done partially in advance of and partiallysimultaneously with the commencement ot the staple-forming operation,the cutting being effected by a plunger-'30 in shearing relation withbushing 181 through which the wire is fed. This `wire is hereinbeforekreferred to as a locking wire and is indicated at 180. fitter it is tedt irough the bushing 181 it passes between the pin 31 and the Yface ofkplunger 30 through a iiared `eye 182 `in the cap Ll5 to a stopconsisting of the overhanging end 183 of a small oii-setbar 1811fastened to the cap over the eye, bysci'ewslS. The feeding of this wireis done by a pair or feedrolls 20() mounted on shafts 201, 202 theformerbeing driven by bevel-gears 203 common tothe differentlockorniers andvhereinafter further described in connection with thenoperating ymeanscommento the several lock-'formerav These reed rolls are disposed toeedvertically, and located beneath and with their direction or feed insupported in a bracket :2.10 secured to the'bot tom or the member Abundle or this wire bent to form the staple has` itsoperating end 31Lreducedvin width sniiiciently to pro? vide Ispaces at the top and bottomsides thereof and betweenit. and thetop and bottoni walls or the lgrooveor slideway 33 suilicient to accommodate the legs or the staple. Thispin is operated by a `bell-cranl-lever 250 actuated in turnintermittently by a bar 2419 secured by screws 251, for instance, to thewidened portion of the plunger., such bar having lingers 25:2 and258these lingers engaging the protruding end 254i of the bellcrank-leverandshitting` it and tne pin upon each reciprocation of the plunger.

Eachlockfformer also has two pairs of kralineinent with the bushing 181.They are 'Y isok eil

together as the slide advances by the swing,

ing of the fingers, and this is caused and the 'lingers made to open andclose to a line intersectine; the line of feed of the strand by camslots 201 therein and pins 262 engaging the slots and carried by theslide 70. rllhese lingers are for guiding the strand wire and bringing'it into alincment with the matrix7 an opening' worlrV permitting` thestrand to pass, spliced portions of such strand beingalso accommodatedand the woven fabric being permitted to swing' free of the fixed die, aswill be hereinafter shown. The stay wire 20 is guided in a guideconsisting` of an integral part 300 of the cover l5 and preA sentinfr aleaning` standard 301 with a latch SO2 pivotedthereto as at 303,suchlatch having` a jaw 304e with an interior shoulder beveled as at305`r the jaw being; Irooved at 306, the end of the groove towards thedirection from which the wire comes beingv flared as at 307 tofacilitate the entry of the wire. T ie latch is yieldingly held closed bv a spring' 308 and bolt- 309 the latter attached to the latch, and thespring` bearing' between a nnton the bolt and the standard.` The wire isforced out of this groove by a cam carried (with as many more as may berequired) upon and operated by a shaft 312 common to all of these camsand to be hereinafter alluded to. This cam consists of a plate 310formed with hub 311 fitting upon the shaft and secured thereto by aspline and set-screw 3M. rEhis shaft is driven from the shaft 212, andat the same speed as it, by sprocket-wheels 890 and chain 391. Aswill bepresently shown. during the downward movement of the cam with the shaftit bears upon the stay-wire 20 and coacts with the other cams inforcingv the wire into the matrices. For this purpose the bearingf faceof the cam of a configuration to force the wire from the guides 306 tothe matrices and before' this action the predetermined length of staywire is measured off and si inultaneously with the commencement of themovement of the wirer it is severed rilhis finishes the description ofoneof the lock-forming' mechanismsy and as before mentioned there aresiX of such mechanisms all identically the same.

These lock-forming;` mechanisms are operated in unison by means commonto all as follows T he several feed devices y (rolls 200, etc.) receivemotion from the shaft 20/lbefore mentioned, the motion being`transmitted through the gears 203 also above 270 in thc bottom of theframe mentioned and through it and pinion 121 and shaft l20vfrom initialpower represented ly pulley 12S. The gears 207 and are mounted on oneand the same stub shalt the gear 206 on a different stub shaft. and thegear 205 on the shaft 204i, and the gear 209 on a shaft y212transmitting` power to the stays-wire twisters to be hereinafter furtheralluded to.

The stay-wire is drawn from a coil (not shown) suitably located andacross the several l ocl -formers and' through the ,guides to 'position20, and measured and eut olf by the followingY means: Stay-wire 20 issupported and guided between the guides 306 of each lock-former byintermediate guides comprising brac iets G00 having a member 601corresponding` to the standard h and having` a latch 602, and coaetingcams 6l() on shaft 312. The se-vering of the stay-wire is done by acutting' tool 320 mounted rigidly upon a collar i023 secured Upon ashaft 31.2 and rotating in shearing relation .vith a stationary cutter132]. counter-sunk in a bracket 322 and fastened Athereto by a clamp1822, the bracket being fastened to the frame member 2 by cap screws1324-. a bushing 321 in the bracket servingy as a guide for the wirewhich is drawn from a reel suitably' located` by a yielding feed device.

This yielding' feed-device consists of two pairs of feed-rolls 33,0331mounted in a carriage horizontally slidable on a slide Sell bolted tothe lun` 322, the carriagey beingn constructed to partially enclose thesliden the edges of which are rabbeted and ene b v the enclosin edges ofthe carriage which are. also rabbeted as at M5. This carriage consistsof a casting Sil-0 and a plate 346 in the space between which the feedrollers and two pairs of driving' gears and 336 are mounted on pins 350,351, and the opposite ends of the lower pins (i, 358), being` diminishedand set in holes in the casting and plate while the upper pins (350.852) are secured in place by set-screws 360` by which may be securedadinstinent to regulate the pressure of the rolls upon the wire. Thiscarriageis caused to move in one direction by the feed rolls creepingvalong the wire during the interval that its progress is arrested by theoperation of the cuttingtool 320; and it is returned to its initialposition by a cam 370 operated by shaft 175 upon which it is rigidlymounted`r the cam acting on a roller 371 on the carriage.4 This creepingback of the carriage provides for a continuous rolling of the feedrollers along the wires which has the advantage of obviating abrasion ofand damage to the galvanized or plated surface of the wire. The end lofthe il o ` Ytei-ent lengths.

Two pairs ot cams ot the same nature as the before-mentionedcams 310 are mounted7 one pair at each margin wire of the fence, andthey all work in conjunction with standards 1001 and 1011 and have fortheir' function to depress the stayevires, each of the standards having`one of the spring' latches 302 carried thereby and operating' in thesame manner as those before mentioned. In order to give a lead to thespiral formation of the coil, the end of the staywire to be coiled issupported on a level with the horizontal grooves 6i' in the dies 50, byan inclined bottom or seat 1005 hetween the leaning' standard 1011 and apair ot vertical lugs 1006 located opposite to the standard 1011. rIhepair of these cams tarthest from the t'eed rolls 330, 331, are indicatedat 1010 and 10127 the cams 1010 being' arranged contiguous to the innerfaces of 1011 and G andthe other cam 1012 contiguous to the standard10015 bot-h cams being in position to act upon the end to be coiled andbend it down to lie across the top of the head and in the. path of therevolving' hcolr.- The top of the head is of conical form and in orderto cause the bent-down end of thel stay-wire to assume a position lying;along` the surface of this cone and in the path of the hook the cam 1010is shorter than 1012 and has its end rounded o concentric with the pivotot the cani and of a rlength to depress the stay-wire end to therequired extent; and the cam 1012 is ot suitcient-ly greater length tosupplement the The pairo'f cams nearest to the feed. rolls are indicatedat 1020 and 1021, the cam 1020 being` struc-y turallythe same in allrespects as cam 1010 excepting that its shapey is reversed and it ismade riglitdiand instead of lett-hand- The Cain 1021 consists ot acurved linger secured to a 'collar 1023 mounted on shaft 312, thefunction ot which is to carry this cani and cutter 320 before mentioned.The action ot these cams and the cams 810 before mentioned issimultaneous, and the hook 909 so timed in its action to meet thestay-wire end immediately after it has been bent down to the conicalsurface.

A. bar 100 common to all the loclr-tormers rests slidably on the beam 4and engages a lug 101 on the underside of the slide. This bar is made tooperatein unison with the cam 74 by a pair ot cams 102 also mounted onshaft 73 and engaged by trundle rolls 103 carried by arms 1011 fastenedto the bar 100. rl`liese cams 102 co-act with the cams 74 as doubleleaders in imparting the required intermittent reciproca-tive operationto the die 50. This shaft is driven from a driving shaft 120 (theinitial source of power in the machine) through a train consisting otafpinion 121y gear 122, pinion 123, and gear 1241 on such shaft 73, thegear 122 and pinion 123 being` mounted on an intermediate shatt 125; andthe driving' shaft deL rives its power troni any available source by acombined fly-wheel and pulley 126, belt 1200 and fjiulley 1201 andcounter-shaft 1223.

The plungers 30 and /10 are operated bj: a pair ot slide-bars 150 151connected to the several plungeis by connecting` rods 152. the end ofrod 152 being); `formed with a vertical pin 154- engaging a hole 155 inthe crosshead 43 and the end plunger 30 .is torlred to receive the endof rod the connection being made by a pin 156. The connection be tweenthe oppositeends et the rods and the slide-bars is effected by pins 157and 15S. These slide-bars are actuated in the operation ot cutting' theblank torining the staple and forming the lock from the staple by cams160, 161 through slides 162 103 in the torin of frames enclosing thecams and carrying rollers 164? 105 beaiiing` upon the Canisn the returnmovement being imparted by caras 10T 108 and rollers 169, 170; while theconnection between the slide-bars and slides 1027 1033 consists o'tengaging hooks 171. 172, formed respectively on the slide-bars ,andslides. These slides 162, 103 are guided in the slideways 2 and areprevented trein upward displacement by the cap 2". These rains 10th 16h10i" and 100 are mounted rig;- idly upon a shaft 175 having powertransmitted thereto trom the shaft 7? throuo'b initrefgijears 170 and1711 lfleietoioi'e therel has been considerable disadvantage experiencedin collecting` the Woven tabric as it lett the machine. owing to the'inet that the .vindii'ig' up or rolling' ot the iabric was of necessitydone intermittently. Another disadvantage was experienced 'troni theiincreasing` diameter oil: the roll being' woundgowing tothe tact thattliev'indind' drum was caused to exert its pull directly upon the fabricin the machine, the variation in pull duel to the increasing diameterbeing neutralized by a `manual adjustment A c* cording to my inventionthe variation in pull ot the wind-up is automatically neutralized y byconstant speed pulling-roll; and. means intermediate of the pulling'roll and the tabric in the machine takes up suticient fabric to leed thecontinuously rotating' pulling roll during` the time the gtabrie is heldstationary by the clamping` Aiction ot the dies. The constant speedpullingF roll is grouped witha wind-up roll 1201 and a roll 1202-toincrease inea-Ass the'extent to which the web or fabric indi` cated at1205 is wrapped around the pulling roll. This latter roll (1200) isdriven constantly by sprocket wheels 1200 and 1207 and chain 1203, shaft1210, pinion 1209 and gear 1211 and the wind-up roll 1201 is 'driven bya bet 1220 looped around pulleys k1221 and 1222 the former on thecounter shaft 1223, before mentioned, and the latter carried by theframe 1224 in which these rollers arev mounted and driving` a pinion1225 inter meshing with a gear 1220 driving thenroll 1201. 1n order toaccommodate faln'ics with. differently spaced stay-wires theshailt 1210is mounted in an adjustable hearing 212 clamped in place by screws 1213and adjustf ed by screw 1214. The take-up y.mechanism consists of a drum1230 mounted rigidly on a shaft 1231 journalcd in a pair of'boxes 1232in vertical slideways .1233 formed on the upper ends of a pair ofstandards 1234 braced `by stays 1235 and 1236. rl`he shaftends extendthroughathe bones and have connecting rods 1237 mounted'thereon and prfvided at their lower ends with trundle rollers 1233 which bear upon cams1239 mounted rigidly on shaft 73. rlhe rollers and ends of theconnecting rods are mounted on'a pair of kshat'ts 1243 journaled inboxes `12%0 guided in slideways 1241. The cams are timed to raise thedrum during the period the dies are open and permit it to fall duringthe period the dies are closed. The fabric is looped over this drum. f

This completes the detailed description of the machine, and in order tofacilitate the ready understandingthereof l will now set forth brieflythe manner in which it/operates.

Operation.

The strand wires 12, 14e, and 15 arek lirst threaded upwardly throughthe coilers 802, the marginal strands 12 and let through the -twisters900 and the intermediate strands l5 through holes 270 in the frame ofthe locking mechanism and between the lockforming dies 50 and'G?) of thcvarious lock-forming mechanisms. From mechanisms and twisters they areall taken over drum 1230 and around thepullingroll 1200 and roll 1202tothe wind-up roll V1201 to which latter they are fastened. rEhe staywire is then threaded betweeny the feed rolls 330 and 331, throughbushing 321 over Vcutter 1321 and through the guides 3,16 lfuntheseplungers 30 (Figures 161,15, 16 and 17) advances in shearingrelationwith the bush- 181 in its particular lock-forming mechanism andcuts off a staple-length, and con tinuing to advance forms the staple.

' shown in `Figures 11 and 1,5, by foldingthe endsover the pin 31previously inserte-d in th'epath of the blank. rlust before the plun-250thus withdrawing the pin 31. linmediately following the withdrawalkof the pin `the second plunger 10 advances and drives thestaple ahead ofit towards the dies. `lust before the forward ends ofthe staple 180 pass"through the hole 60 the die G3 is brought into contact with the die 50by means of cam 741, roller 75, and slide 70.

Continuing inr its forward movement the plunger 410 drives the stapleinto the matrix thus forming the lock. Simultaneously with thedepression of the stays 20 by cams 310- to the position 20, the ends ofthe stays are depressed by the cams 1010, 101.2,and 1021, thus bringingthe ends into the path of the lingers 909 by Which'these ends are`engaged and twisted or coiled as at 1909 around the marginal strand 111(Figs-27, v23, 29, 30, 31, 32, 33, and 341).r Each coiler or twister isso timed as to engage the endl of the stay immediately it is depressed.The lockf0rming step and twisting or rcoiling step are simultaneous, andthe matrices are opened immediately the lock is formed. The

loperation thus far described completes the wear/'ing of the fabric, andthe elevation and the winding up of the latter is the final step. Thiselevation and winding up is caused by the rotation of the drums 1200,1201, 1202 and reciproc-ation of the `drum 1230, the latter beingoperated by cams 1239, and the .function thereof being to take-upsufficient length of strands to`permit them to be' held stationery inthe dies from the time the dies Aare closed until they are opened again.It

must be understood that the pulling drum 1200 rotating continuously atuniform speed in unison with themachine, must be supplemented'by meansforfeeding the fabricto the drum during the stat'ionaryperiod. This isdone by the elevation of the drum 1230 and consequently the taking up`of the fabric during the time the dies are open, and thek lowering ofthe drum and consequently the jfeedingfabric during such stationaryperiod. During this elevation of the fabric the strands are pulledthrough the coilers 305 and coiled. 1n order to obtain a uniformity ofposition of the curves produced by the coilers relatively to the stays,the coilers are driven in unison. Just previous to the commencement ofelevation `of the fabric, the cam S62 through the intermediatelmechanisms described operates the clutch 360 vand brings lthe 'shaft852 and conseger reaches the end of its stroke, the linger r25,3 (Fig.15) operates the bell-crank lever quently the coilers into action.Before the elevation is completed the mechanism 863 (Figs. 1.4, and (l)throws out the clutch and throws .i the brake, thus stopping the coilerswhile the 'fabric is'still being elevated and causing them to act astension devices. Si. feature ot this operation, due of course to the'novel construction and combination ot parts before described, is thatthe lock-torming wire is `fed in a line parallel to the strands with theadvantage that they (the lock-torming wires) avoid all obstructions; andthe staple strucl; therefrom is maintaineduntil linal formation in thevsame plane in which it is formed, with the advantage ot' simplicity ofconstruction and operation of the machine.

rlhe gear 705 is so cut that each tooth produces one-quarter of an inchtravel of the periphery of the1 leed rolls 330 and 331, thereby enablinga predetermined length oi stay wire to be :ted during the intervalbetween the times the cutter 320 passes through the line of the wire(indicated at 20. see Fig.
